Abstract

Background: The safety and efficacy of treatment with P2Y12 adenosine-diphosphate receptor inhibitors (P2Y12-RI) before coronary angiography among patients with non-ST-segment elevation acute coronary syndromes (NSTEACS) are questionable. Aims: To assess the pretreatment rate with P2Y12-RI and its association with ischemic and bleeding risks among patients with NSTEACS. Methods: The study comprised patients with NSTEACS referred for coronary angiography and included in the Acute Coronary Syndrome Israeli Surveys between 2013 and 2021. Patients were divided into two groups according to the timing of P2Y12-RI loading concerning coronary angiography: pretreatment and posttreatment. The primary endpoints were 30-day major adverse cardiovascular events (MACE; composite of cardiovascular mortality, myocardial infarction, stroke, stent thrombosis, and urgent revascularization) and 1-year all-cause mortality. Results: Of 3076 patients, 2423 (78.8%) received pretreatment with a P2Y12-RI, and 653 (21.2%) received P2Y12-RI posttreatment. Prasugrel and ticagrelor were used more in the posttreatment group compared to the pretreatment group (16% vs. 6% and 38% vs. 25%, respectively, p < 0.001 for both). No difference was observed in the rate of 30-day MACE comparing pretreatment and posttreatment (5.3% vs. 2.2%, respectively, p = 0.62). A sensitivity analysis of 30-day MACE among patients from the 2021 survey demonstrated similar results (2.5% in the posttreatment group vs. 8.0% in the pretreatment group, p = 0.13). There were no differences in 1-year all-cause mortality rates between the pretreatment and posttreatment groups (4.8% vs. 3.8%, p = 0.31). Conclusions: Among patients with NSTEACS referred for an invasive strategy, the P2Y12-RI posttreatment strategy was associated with similar 30-day and 1-year MACE as the pretreatment strategy. These large-scale, multicenter, real-world data provide reassurance on the safety and efficacy of delaying P2Y12-IR until after coronary stratification to improve clinical decision-making.
